I'm in the process of refactoring the analog tuner.ko module such that 
analog tuner modules will use the same internal api as dvb_frontend * 
modules.  I have completed phase one of this refactoring process this 
past weekend, but there are still some bugs left that I must fix before 
publishing the work.  I had to leave town unexpectedly, and it's 
difficult to work on this remotely.

In phase 2 of the refactoring, the tda8290+tda8275(a) drivers will 
undergo a structural redesign, in which support for the tda8295 and 
tda18271 will be added.

In addition, tuner-simple will need its own redesign, although I am 
saving that for last -- but that's irrelevant to your question.

What device do you have that uses the tda18211?  So far, I am only aware 
of one device available on retail shelves that use the tda18271 -- I'm 
curious what you're working with.

Regards,

Mike Krufky
